Just a reminder that as seeding progresses, phosphate starter nutrient is required to ensure uniform rapid crop emergence. Banding starter phosphate at the recommended safe rate applied with or very near the seed is important for healthy development of crop seedlings, including healthy root growth.
If the soil test called for higher than the safe rate of phosphate applied with the seed, split apply the phosphate. This can be done by applying a safe rate with the seed and the rest of the required phosphorus can be placed in a sideband or midrow band with the rest of the nutrients.
Practicing 4R nutrient stewardship for each of the nutrients is important so that the correct level and balance of phosphorus can be applied to meet the crop needs. Following the 4Rs of nutrient stewardship, the Right Source applied at the Right Rate, Right Time and Right Placement, is a strong fit for managing phosphorus for a healthy crop, as well as minimizing the risk nutrients moving into the environment.
